House of Lies - Interview with Ben Schwartz

Jean-Ralphio has become kind of like a big deal. Is he based on a real-life tool?
No, the role was originated by the writers. They wrote this role called Jean-Ralphio and then asked me if I would do it. I, of course, said yes. In my head, I think of the douchiest thing somebody can do in a moment. But I think he thinks that he’s always nailing it. Like, he thinks he’s saying the right thing at the right time, that he’s just crushing life. So I just play him like that, like an ignorant narcissist, kind of.

At one point, you sing one of your punch lines: “I’m flu-hush with cah-hash.” It’s become an Internet catch phrase.
It’s crazy! The Internet has been so nice and polite to me. There’s another one I sing [breaks into sing-song-y voice], “I got run over by a Lexus.” That one’s a ring tone now. It’s insane.
